Justification:
The population is estimated to number about 1,000 mature trees and the species is restricted to a small area in the southwest of Andohahela (Ranopiso). At one stage all seed being produced was being harvested for the international horticultural trade, however, since the listing of this species on CITES Appendix II the situation has probably improved. The leaves of the plant are also exploited for thatching but this may be less detrimental to the survival of the species. It is listed as Vulnerable based on the population size, but if there is any indication of a significant population decline the species would warrant listing in a higher threatened category.
